ResumoThe paper introduces an effective method for approximate conversion of spline surfaces. The method uses mainly geometric continuity conditions, parameter transformations and nonlinear optimization techniques. Degree reduction to bicubic and biquintic surfaces is introduced, curvature oriented segmentation is developed. The method can be extended to merging spline surfaces and to spline approximation of offset surfaces.
